EP2615227B1 - Remote control key for a motor vehicle - Google Patents

Description

The invention relates to an ID transmitter (radio key) for a motor vehicle. In particular, the invention relates to an ID transmitter with a communication electronics, which is accommodated for carrying out a non-contact access authorization to a motor vehicle in a housing.

Such radio keys wirelessly process an authorization dialogue with vehicle electronics to check the authorization of a carrier of the radio key for access to the automobile.

In most cases, such an ID transmitter contains an emergency key for mechanically unlocking a door of the motor vehicle in the event that the electronic and wireless communication, e.g. due to interference or lack of energy, is not possible. For this purpose, the ID transmitter has a receptacle in which the emergency key is at least partially receivable, e.g. can be inserted or latched.

If the emergency key permanently housed in the housing of the ID transmitter, the housing has a latching mechanism, so that the emergency key is locked in a latching position in the receptacle in the housing.

An ID transmitter of the type mentioned is, for example, in the patent application DE 103 31 087 A1 disclosed.

The DE 195 05 190 A1 also describes an ID transmitter with retractable and removable emergency key, the emergency key has a tightening eye.

From the DE 103 31 087 A1 an ID transmitter is known, which has an inserted emergency key with a movable Anringöse.

It is an object of the invention to improve an ID transmitter of the type mentioned in its design and ease of use.

This object is achieved by an ID transmitter with the features of claim 1.

The ID transmitter according to the invention has an eyelet component coupled to the emergency key. The Ösenbauteil used with its at least one eyelet to couple the ID transmitter, for example, to key rings or other support means.

The Ösenbauteil is movable against the emergency key. It is arranged such that, when the emergency key is in its latching position in the receptacle of the housing, it can be brought into a coupling position with a second latching mechanism. This second locking mechanism locks the movement of the Ösenbauteils against the emergency key.

According to the invention, the emergency key is thus locked at any time in the same position in the housing when placed in the housing, and the Ösenbauteil can either assume a position in which it is movable against the emergency key, e.g. is retractable and pivotable, or on the other hand locked against the emergency key and locked.

The position of the emergency key does not need to be changed accordingly for a change in position of the Ösenbauteils, instead, the Ösenbauteil can be arranged against the emergency key movable or immovable.

The ID transmitter according to the invention allows a change in position of the Ösenbauteils such that the Ösenbauteil can be used to carry or attach the entire ID transmitter. This is possible if the Ösenbauteil is placed opposite the emergency key in a position such that the eyelet is accessible for attachment. Since the emergency key is securely locked in its detent position in the ID transmitter, the Ösenbauteil can take over the carrying function for the entire ID transmitter.

In addition, the emergency key can be removed from the ID transmitter, namely when it is disengaged from the first locking means. In this separate arrangement of emergency key and ID transmitter the Ösenbauteil is still coupled to the emergency key and can be used to carry the emergency key. Thus, there is an inseparable coupling of the Ösenbauteils with the emergency key, the emergency key is separable from the ID transmitter by releasing the first locking means.

The movement of the Ösenbauteils against the emergency key is when the emergency key in its locked position in the ID transmitter is fixed by the second locking means.

In this way, the Ösenbauteil can be brought, for example, in a recessed position and fixed there by coupling with the second locking mechanism, for example, to avoid protruding components on the ID transmitter. On the other hand, when the Ösenbauteil is not brought into engagement with the second locking mechanism, the eyelet against the emergency key depending on the attachment between eyelet and emergency key swung, pulled out or even rotated to the eyelet for access and attachment of the entire ID To make donors accessible.

Since separate locking mechanisms for the emergency key and the Ösenbauteil are provided, the security is increased, since an accidental disconnection of ID transmitter and emergency key is less likely. In addition, the user of the ID transmitter can select at any time whether he wants to use an ID transmitter with or without an eyelet component without changing the position of the emergency key in the ID transmitter.

As Ösenbauteil in the context of this invention, each component is to be considered, which has an opening which is suitable for attachment to a wire, key ring or rope. It is therefore generally a continuous opening with a closed circumferential line, so that a secure attachment by means of this eyelet is possible.

An emergency key in the sense of the application is understood to be any device which is capable of lifting a lock on a motor vehicle by mechanical action. Such emergency keys are usually made of plastic or metal and can be formed in one or more parts. The receptacle for the emergency key in the ID transmitter can be formed inside the housing or in a wall of the housing of the ID transmitter. It is essential that the emergency key can be locked in its detent position in the ID transmitter.

In one embodiment of the invention, the Ösenbauteil is pivotally attached to the emergency key and the second Locking mechanism locks a pivoting of the Ösenbauteils against the emergency key.

A pivoting of the Ösenbauteils can be realized by a bolt which pierces the Ösenbauteil example in its open eyelet and another bearing opening and is mounted in recordings on the emergency key. It is particularly advantageous if the emergency key has a corresponding recess, so that the Ösenbauteil can be pivoted during pivoting in this recording of the emergency key. This results in a particularly compact emergency key.

According to the invention, a single actuating means is coupled to the first latching mechanism and to the second latching mechanism in order to act on the latching mechanisms. When acting on the locking mechanisms is released according to the emergency key or the Ösenbauteil.

The unlocking of the locking position via actuating means allows a secure recording of the emergency key in the ID transmitter and the Ösenbauteils in its rest position. Here, any known locking connections can be used, for example locking lugs with spring preload or the like. The actuating means may be correspondingly pushbutton or slider, with which the locking means can be disengaged. According to the invention, a single actuating means is provided, which can act on both the first and the second latching mechanism. In this case, the latching mechanisms are designed so that upon actuation of the actuating means, the latching mechanisms are released successively. First, the second locking mechanism is released, that unlocks the Ösenbauteil in its movement relative to the emergency key. If a further actuation of the first latching mechanism is released and the emergency key unlocked.

The further actuation may be a second actuation, that is, a second pressure or also a continued actuation, e.g. be a further pressing a push-button.

In a preferred embodiment, the actuating means is designed as a push-button and the downstream release of the locking mechanism is effected by different stroke paths.

If the pushbutton is pressed in for a first stroke, the
solved second locking mechanism. If the push button is pressed further, the second locking mechanism is released and the emergency key is released.

According to preferred embodiments of the invention biasing means are provided on the Ösenbauteil and / or the emergency key, which are to be overcome in order to bring these components in their locking positions. It can therefore be overcome, for example, spring forces to bring the emergency key in its locked position, and to bring the Ösenbauteil in its rest position. If the locking means are released, the components, ie the emergency key or the Ösenbauteil, pushed out of the detent position, so the emergency key so for example, partially from the recording and thus from the ID transmitter out. The Ösenbauteil is also urged from its locked position by the second locking means in a relation to the emergency key changed position. This increases the ease of use, since the accessibility is improved after unlocking the locking means for a user.

The Figures 1A and 1B show two views of the ID transmitter according to an embodiment of the invention. The ID transmitter consists of two coupled housing components 2a and 2b. The housing component 2b, which in Figure 1A can be seen as overhead component is referred to in this description as a cover component. The component 2a is referred to as a floor component. The side of the ID transmitter 1, a push-button 3 is arranged, which is accessible to a user of the ID transmitter from the outside. In a recess 5 of the housing an emergency key 6 is added. The emergency key can, as will be described below, be released by pressing the push button 3 for removal from the recess 5. With the emergency key 6, an Ösenbauteil 7 is connected, which is pivotally received on the emergency key 6 in a recess of the emergency key 6.

In FIG. 1B can be seen that the Ösenbauteil 7 is sunk in the position shown in a recess of the housing part 2a and substantially aligned with the surface of the housing member 2a. As will be described below, the eyelet member 7 can be pivoted out of this position to form a carrying eye for the entire ID transmitter 1. In this process, the emergency key 6 remains in its position in the receptacle. 5

In the in the Figures 1A and 1B configuration shown results in a compact and stylish ID transmitter, without protruding components.

In FIG. 2 the ID transmitter is shown with the lid member 2b removed. It is fundamentally possible for electronic components and switching components as well as operating elements to be accommodated in the ID transmitter, but these are not shown in the context of this description so as not to distract from the invention. The cover 2b may, for example, have push buttons for triggering remote control functions.

FIG. 2 shows that the emergency key 6 is received in a receptacle 5, which has a boundary inside the ID transmitter, which is formed integrally with the housing member 2a. The emergency key 6 is enclosed with its key shaft in the elongated receptacle 5, which delimits him from the other components of the ID transmitter recorded. It is shown that a spring element 10 is arranged with a spring tongue 10a in the housing. Lateral fastening parts of the spring element 10 rest in the housing and a spring tongue 10a exerts with a free end a spring pressure on a portion of the Ösenbauteils 7. In the illustrated position, however, the Ösenbauteil 7 is locked in its position, as will be described below. The Ösenbauteil 7 is biased by the spring tongue 10a, however, to yield when released from the position shown the spring pressure and swing out and make the eyelet accessible to the user.

FIG. 3A shows the arrangement FIG. 2 , wherein for better clarity, the spring element 10 is removed. In this illustration, other components become visible. It can be seen that the push-button 3 is biased by a coil spring 11. In addition, a latching mechanism is coupled to the push-button 3, which is provided from an elongated shaft 15 with lugs 15a and 15b. As will be described in detail below, the projection 15a forms a releasable holding means for the Ösenbauteil by engaging in the Ösenbauteil 7. The projection 15b secures the position of the emergency key 6 against being pulled out of the recess 5. The components are in FIG. 3B shown more clearly.

In FIG. 3B It can be seen that the projection 15a engages with a nose in the eye of the Ösenbauteils 7. By this engagement, a pivoting of the Ösenbauteils is blocked, even if the Ösenbauteil is under bias by the spring element 10. The projection 15b is located above a notch in the emergency key 6, which causes a locking of the emergency key 6 against withdrawal, as will be described below. It is in the FIGS. 3A and 3B recognizable that by a pressure on the push button 3, the shaft 15 can be moved against the spring force of the spring 11, so that the lugs 15a and 15b change their position to the emergency key and the Ösenbauteil received therein.

The projection 15c is formed in this embodiment, to form a stop for a stroke limitation with swiveled eyelet when pressing the push button 3. If the eyelet is in the locked position in engagement with the projection 15a, the projection 15c prevents the pushbutton from being pushed in beyond the release position for the eyelet component 7. Only when the Ösenbauteil 7 is released from the engagement of projection 15a and is pivoted out of the path of movement of the projection 15c, the push button 3 can be pressed so far that even the emergency key can be disengaged from the approach 15b. In this example, a double actuation is therefore required with the Ösenbauteil pivoted to release the emergency key. This prevents accidental release of the emergency key in the event that only one release of the eye member is intended.

The FIGS. 4A and 4B show a corresponding position of the arrangement of the FIGS. 3A and 3B , wherein a pressure on the push button 3 has caused an adjustment. The projection 15 a is with its nose out of engagement with the eyelet of Ösenbauteiles 7 passes, so that the Ösenbauteil 7 has been released and is pivoted about its pivotal support in the emergency key 6. The displacement of the pushbutton 3 and the shaft 15 and the lugs 15a and 15b is in FIG. 4B clearly visible. However, it will be further appreciated that while the nose of the lug 15a has been disengaged from the eyelet, the lug 15b continues to overlie the notch of the key 6.

The key 6 is still not removable from the housing in this position that the projection 15b locks the key 6 against being pulled out. If the push-button 3 is released in this situation, the Ösenbauteil 7 remains unlocked, the emergency key 6 remains in the locked position.

In FIG. 5 the push-button 3 is further inserted into the housing, so that now not only the projection 15a, but also the projection 15b has been disengaged from the associated components. The lug 15b is no longer engaged with the notch and the emergency key 6, so that the emergency key can be pulled out of its receptacle 5 in the housing 2a. In this position, it can be seen that the Ösenbauteil 7 is pivotally received in the emergency key 6, and in that a recess is provided in the housing 2a, which allows a swinging and pivoting of the Ösenbauteils. Further, the recess in the emergency key recognizable, which is adapted to the outer contours of the Ösenbauteils to accommodate this in the restricted position. The Figures 6A and 6B show the push button 3 with the coupled linkage 15 and the lugs 15a and 15b. In particular, in FIG. 6A recognizable that a downwardly projecting approach of the element 15b can engage in a corresponding recess in the emergency key. The emergency key 6 can only be removed if the projection 15b is brought out of engagement with the recess in the emergency key by pressing the button 3.

Overall, all drawings show that a pressure on the push button 3, with adjustment of the linkage 15 by a first, small stroke initially brings the projection 15a out of engagement with the Ösenbauteil 7 and this swings (under the action of the spring force of the spring element 10a). With continued actuation of the pushbutton 3, in particular when impressions to a larger stroke, the approach 15b is disengaged from the recess in the emergency key 6, as in the Figures 6A and 6B shown. In this position, the emergency key, for example by pulling on the swung-out eyelet, be removed from its recess. If the pushbutton 3 is not pressed so far, the emergency key is still secured in the housing before, the Ösenbauteil is swung out and can be used to carry the ID transmitter. If this function is no longer needed, the Ösenbauteil 7 can be pivoted back into position, as in the Figures 1A and 1B is shown. For this purpose, the projection 15a has a bevelled surface such that upon pivoting of the Ösenbauteils 7, the linkage 15 against the spring force of the spring 11 is pushed far from its rest position, that the Ösenbauteil 7 is pivoted and the lug 15a back to the rest position, in which engages the projection 15a in the eye opening of the Ösenbauteils 7 and secures this.
